Project scenario:
Image recognition labeling tool labelme
Environment: window10+python3.9+labelme

After python and script paths are added to environment variables, install directly with pip install labelme
When entering labelme in cmd, QtPy5 error may appear, the label interface cannot be opened, and the picture does not respond, etc.
[WARNING] __init__:update_dict:17 - Skipping unexpected key in config: num_backups
Cause Analysis:
Most of the problems are because there are Chinese in the python installation path! ! !
solution:
First check whether there is Chinese in the Python installation path. If so, uninstall python and reinstall it to a pure English path, which can basically solve most of the problems.
